Description

A composition for improving hair or scalp condition comprising a plant extract as an active ingredient {A composition for improving hair or scalp condition comprising a plant extract as an active ingredient}

It relates to a composition for improving hair or scalp condition comprising a plant extract as an active ingredient.

Hair is an appendage of the skin and is divided into a hair shaft corresponding to the outer part of the skin and a hair root part surrounded by hair follicles inside the scalp. The hair of the hair shaft is composed of three parts: cuticle, cortex, and medulla from the outermost part. The cuticle is a stratum corneum formed to protect the inside of the hair from external stimuli and determines the wettability and gloss of the hair. The cortex and medulla are responsible for maintaining the shape of the hair and are filled with fibers made of a protein called keratin. Hair is formed in hair follicles at the hair root, and there are about 100,000 to 150,000 hair follicles on the scalp. The hair follicle is in the form of a three-layer cylindrical shape surrounding the hair in the center, and consists of the dermal sheath, the outer root sheath, and the inner root sheath from the outermost. The root part of the hair follicle is called the hair bulb, and hair is generated and grown in that part. It is a bulb-shaped convex shape at the bottom of the hair root, and contains a structure called the dermal papilla, which has a papillary protrusion. The dermal papilla is a central part that controls hair growth. It comes out of the dermal cell layer and has many capillaries and autonomic nerves, supplying various nutrients, protein synthetase, hormones, and oxygen necessary for hair growth. The dermal papilla is also the site where male hormones act in male pattern baldness. The part where cell division occurs according to the control in the dermal papilla is called the matrix, and cell division and proliferation are constantly repeated. There are sebaceous glands in the diagonal direction of the dermal papilla, which provide luster to the hair and supply oil.

The cycle of hair refers to the cycle of creation and extinction of each hair. The mother cycle repeats a certain cycle of development, growth, hair loss, and development. Usually, the corresponding cycle is classified into anagen, catagen, and telogen. The anagen phase is the time when hair cells divide and new hair bulbs are created, and body hair begins to grow in the hair follicle. It is a period in which hair grows due to active hair follicle activity and cell division. It lasts about 2 to 6 years and accounts for 85% of all hair. The catagen phase is the time when hair cells stop dividing and start preparing for hair loss. The hair root goes up, the dermal papilla is detached from the hair bulb, and the hair bulb contracts the tissue and changes to become thin and long like a club. It takes about 2-3 weeks and accounts for 5% of all hair. It is the period when the dermal papilla and hair fall off and the dermal papilla turns round, and the cell activity of the hair follicle completely disappears. The hair falls out due to being pushed by growing hair or by mechanical action such as combing. It accounts for 10% of all hair.

Hair loss progresses as androgens or active oxygen stimulate dermal papilla cells. It occurs when dermal papilla cells secrete substances that destroy hair follicles or inhibit the secretion of growth factors that grow hair. When excessive secretion of sebum occurs in the sebaceous glands, inflammation is induced in the dermal papilla, and nutrient supply becomes inevitable, resulting in hair loss. Stress is also one of the factors that cause hair loss. Corticotropin-releasing factor, a hormone involved in stress response, changes the expression of cytokines in dermal papilla cells, induces early degeneration of hair follicles, and suppresses hair growth to cause hair loss.

A major factor in male pattern baldness is the effect of abnormal androgens. Androgens are the collective term for hormones that affect the growth and development of the male reproductive system. Testosterone, one of the androgens, is converted into dihydrotestosterone, an active male hormone, by an enzyme called 5α-reductase. When the activated dihydrotestosterone binds to the androgen receptor (AR) of the dermal papilla in the frontal and parietal regions, a cell destruction signal is transmitted to the DNA of the hair cells. When DKK-1 (Dickkopf-1) and TGF-β1 (Tumor Growth Factor β-1), which are cell apoptosis factors, are produced by this signal, hair cells are destroyed and converted to a catagen phase, resulting in hair loss. Relatively, women have only half of 5-alpha-reductase compared to men, so the frequency of hair loss by the same mechanism is considerably lower than that of men.

In general, hair growth treatment agents that prevent the occurrence of DHT for the treatment of male pattern baldness are common, and Finasteride is a representative example. However, if women take it for a long time, there is a problem in that the probability of giving birth to a deformed child is high and in the case of men, side effects such as erectile dysfunction occur. Recently, studies on methods of using the proliferation of hair follicle cells without side effects have been actively conducted. VEGF (Vascular Endothelial Grwoth Factor) and BMP 2 (Bone Morphogenetic Protein 2) play very important roles, and especially Wnt/β-catenin is in a very important position in hair follicle cell activation and regeneration.

Philadephus schrenckii is a deciduous shrub native to the valleys of the Korean Peninsula. The leaves are specified as edible parts in the food raw materials notified by the Ministry of Food and Drug Safety. Gogwang tree has been known since ancient times to have the effect of clearing heat and detoxifying and relieving spleen.

Securinega suffruticosa is a deciduous broad-leaved shrub native to the foothills of the Korean Peninsula or along sunny rivers. The leaves and fruits are specified as edible parts in the food raw materials notified by the Ministry of Food and Drug Safety. It has been known for a long time that clown clownfish has the effects of active blood seogeun (活血舒筋), strong muscle bone (强筋骨), and tendon hypertrophy (健脾益胃).

Baby Suyeong ( Rumex acetosella ) is a perennial plant that grows wild in the fields or roadsides of the middle and south of Hanbandu. The leaves and shoots are specified as edible parts in the food raw materials notified by the Ministry of Food and Drug Safety. Since ancient times, Aegisuyeong has been known to have the efficacy of clearing heat, clearing heat, diuretic, warming heat, and killing insects.

However, the use of the plant extract for the prevention, improvement, or treatment of hair and scalp conditions is not known, and no mechanistic studies have been conducted. Therefore, the present inventors conducted direct efficacy studies on the prevention, improvement, and treatment of hair and scalp health with plant extracts.

It will be described in more detail through the following examples. However, these examples are intended to illustrate one or more specific examples, and the scope of the present invention is not limited to these examples.

Example 1: Preparation of plant extract

The plant extract contained in the composition of the present invention was prepared by the following process.

First of all, domestically grown wild trees, clownfish, or baby suyeong were purchased, washed with distilled water, and then completely dried in a cool place without sunlight until there was no change in weight. Then, 30% fermented alcohol (30 times, w/w) was added to each completely dried dry matter. At this time, the mixing ratio of the dry matter and 30% fermented alcohol was 30 times the weight ratio. Next, 30% fermented alcohol mixed with the dried product was put in a constant temperature water bath and stirred and extracted at 60 ° C. for 5 hours. The extracted sample was filtered through a housing filter (10 um), concentrated under reduced pressure, and dried to obtain each powder.

Experimental Example 1: Confirmation of 5α-reductase enzyme activity inhibitory effect

The inhibitory ability of the 5α-reductase enzyme of the H. clownfish extract obtained in Example 1 was confirmed.

5α-reductase reduces testosterone to produce dihydrotestosterone (DHT). After reacting rat liver homogenate with testosterone, the ability to inhibit 5α-reductase enzyme activity was measured using a method for quantifying testosterone.

First, 7-week-old male SD rats were prepared and anesthetized using ethyl ether. After laparotomy of SD rats, the hepatic portal vein was nicked, and cold STM buffer (270 mM Sucrose, 10 mM Tris-HCl, pH7.5, 1 mM MgCl2, G-biosciences, USA) was injected into the left ventricle using a syringe. The STM buffer was perfused into the liver until the color of the liver changed from dark red to light pink. Then, the liver was removed, transferred to a beaker, cut with scissors, and then homogenized by adding three times the amount of STM buffer. After the homogenate was centrifuged at 10,000 x g for 10 minutes, the supernatant was homogenized once more to prepare an enzyme solution. The plant extract of Example 1 was added to phosphate buffer (pH6.5), 500 μM testosterone, and 770 μM NADPH (nicotinamide adenine dinucleotide phosphate). Next, the prepared enzyme solution was added and reacted at 37° C. for 30 minutes. After adding dichloromethane to terminate the reaction, centrifugation was performed at 2,000 rpm for 10 minutes. After separating and concentrating the dichloromethane layer, it was dissolved in 50% methanol and quantified using high-speed chromatography. 5α-reductase inhibitory ability was calculated by the formula of 5α-reductase inhibitory ability (%) = [1 - (area value of sample - area value of blank sample) / (area value of test group - area value of blank sample)] × 100 .

As shown in Figure 1, it was confirmed that the clownfish extract was treated with 125, 250 or 500 μg/ml, and exhibited 5α-reductase inhibitory activity in a concentration-dependent manner. These results indicate that the H. clownfish extract is effective in inhibiting or improving hair loss.

Experimental Example 2: Confirmation of cell proliferation and cytotoxicity

It was confirmed what effect the extracts of Kogwangnamu, Hsagi chinensis, or Arabidopsis obtained in Example 1 had on cell proliferation and cytotoxicity on human follicle dermal papilla cells (HFDPC), which are dermal papilla cells.

HFDPC cells were cultured in Follicle Dermal Papilla Cell Growth Medium containing a supplement mix (5% fetal calf serum, 0.5% bovine pituitary extract, 0.5 μg basic fibroblast growth factor, 2.5 mg insulin) and 1% antibiotic antimycotic solution. The HFDPC cell line was dispensed into a 96-well plate at a concentration of 1.0 X 10 ⁴ cells/well and cultured for 24 hours in a CO ₂ incubator controlled at 37° C., 95% humidity, and 5% CO ₂ . Afterwards, the medium was replaced with a medium without a supplement mix, and samples of each concentration were treated and cultured for 24 hours, and the degree of cell viability was measured by MTT assay. The MTT assay is a method for measuring the amount of formazan formed from reduced MTT by mitochondria of living cells. More specifically, each cell was treated with 100 µl of 0.5 mg/ml MTT solution and incubated for 4 hours, then the solution was completely removed and the absorbance of the plate dissolved in DMSO was measured at 540 nm.

As shown in Figure 2, it was confirmed that there was no cytotoxicity at all treatment concentrations, and treated with the extract of Kogwang tree, the extract of Clownfish extract, and the extract of Arabidopsis at each concentration. In particular, it was confirmed that the Gogwang tree extract significantly increased cell growth at a concentration of 25 to 50 μg/ml and the extract of Arabidopsis at a concentration of 50 to 100 μg/ml.

Experimental Example 3: Confirmation of suppression of cell destruction-related gene expression

Changes in cell destruction-related gene expression in dermal papilla cells (HFDPC) were confirmed with respect to the extracts of Gogwangnamu, Hsagi chinensis, or Arabidopsis obtained in Example 1.

Specifically, HFDPC cells were cultured with Follicle Dermal Papilla Cell Growth Medium containing supplement mix (5% fetal calf serum, 0.5% bovine pituitary extract, 0.5 μg basic fibroblast growth factor, 2.5 mg insulin) and 1% antibiotic antimycotic solution. The HFDPC cell line was dispensed into a 6-well plate at a concentration of 2.0 X 10 ⁵ cells/well and cultured for 24 hours in a CO ₂ incubator controlled at 37° C., 95% humidity, and 5% CO ₂ . Then, after replacing the medium with no supplement mix, 50 μM of DHT was treated to induce cell destruction. Then, the extracts of Example 1 were treated and cultured for 24 hours. After that, RNA was extracted from the obtained cells using Trizol reagent, cDNA was synthesized from the obtained RNA using a cDNA synthesis kit (Bio-Rad), and quantitative real time-PCR was performed using the synthesized cDNA as a template. PCR, qRT-PCR) was performed. The RT-PCR reaction was performed under conditions of 95°C for 20 seconds, 95°C for 3 seconds, and 72°C for 30 seconds for 40 cycles. The expression level of the gene was finally analyzed through correction for the GAPDH gene. qRT-PCR was performed using the oligomers shown in Table 1 as primers.

As shown in FIG. 3, it was confirmed that the mRNA of the androgen receptor (AR), which was increased by dihydrotestosterone (DHT), decreased significantly in a concentration-dependent manner when the extract of Kogwang tree extract, the extract of Clownfish extract, or the extract of Arabidopsis was treated. In particular, it was confirmed that all the extracts of Example 1 inhibited androgen receptor gene expression more effectively than finasteride used as a positive control.

Figure 4 is a graph confirming the mRNA change of Dickkopf-1 (DKK-1) upon treatment with the extract of Example 1. As shown in FIG. 4, it was confirmed that the expression of DKK-1, a cell destruction-related factor, which was increased by DHT treatment, was significantly reduced by the extract of Clownfish extract and the extract of Arabidopsis.

Figure 5 is a graph confirming the mRNA change of transforming growth factor beta 1 (TGF-β1) upon treatment of the extract of Example 1, it was confirmed that the expression of TGF-β1 was significantly reduced in all extracts.

The above results indicate that the extracts of Kogwang tree extract, extract of clown clover, and extract of Arabidopsis japonica are effective in improving scalp and hair health by suppressing the expression of genes related to cell destruction.

Experimental Example 4: Confirmation of promotion of cell proliferation-related gene expression

Changes in cell proliferation-related gene expression in dermal papilla cells (HFDPC) were confirmed with respect to the extracts of Kogwangnamu, Hsagi chinensis or Aegis suyeong obtained in Example 1.
